Andrii Nakryiko 7bdadbda1e bpf: Add support for BPF_OBJ_GET_INFO_BY_FD for bpf_link ... [upstream commit f2e10bff16a0fdd41ba278c84da9813700e356af] Add ability to fetch bpf_link details through BPF_OBJ_GET_INFO_BY_FD command. Also enhance show_fdinfo to potentially include bpf_link type-specific information (similarly to obj_info). Also introduce enum bpf_link_type stored in bpf_link itself and expose it in UAPI. bpf_link_tracing also now will store and return bpf_attach_type.
